各种yum源

centos      redhat

一般163的源比较好用

1，进入yum源配置目录
cd /etc/yum.repos.d

2，备份系统自带的yum源
mv CentOS-Base.repo CentOS-Base.repo.bk
下载163网易的yum源：
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

3，更新玩yum源后，执行下边命令更新yum配置，使操作立即生效
yum makecache

4，除了网易之外，国内还有其他不错的yum源，比如中科大和搜狐的，大家可以根据自己需求下载
中科大的yum源：
wget http://centos.ustc.edu.cn/CentOS-Base.repo
sohu的yum源
wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo

理论上讲，这些yum源redhat系统以及fedora也是可以用 的

# The mirror system uses the connecting IP address of the client and the

# update status of each mirror to pick mirrors that are updated to and

# geographically close to the client.  You should use this for CentOS updates

# unless you are manually picking other mirrors.

#

# If the mirrorlist= does not work for you, as a fall back you can try the

# remarked out baseurl= line instead.
